Few places in the sport of whitewater kayaking are as iconic as Great Falls of the Potomac. In 1975, it was here that Tom McEwan and Wick Walker took running vertical waterfalls and extreme whitewater to a new level; and in doing so, laid the foundation for a new chapter in the sport. ‘The Fall Line’ visits Tom McEwan for his account of running the falls for the first time as well as an in depth Great Falls tour with local Geoff Calhoun.
